John M. ALLEN b. 1797, New Bedford, MA

I am looking for the parents of John M. ALLEN, born 1797.He married Mary Jane BULLIS in Jefferson Co., NY 5-4-1820.LDS information says that John was the son of Abraham Allen of New Bedford, MA. I have been unable to find any documentation of this. I would be glad to hear from anyone who might have any knowledge about this part of the family. Carroll
